I also tried out Mining Mike. It's made by Rift Away, the same developer who made Chilling Space and Cyber Space, and has recently been updated for the DK2. It's an endless runner where you guide a mine cart as far as you can without crashing. You can play it in either first or third-person view, though I prefer the former. You can also collect coins to gain a double jump ability. My high score is 919.
